Let me start by saying I am not a lawyer. However, I am a real estate broker who works exclusively in retail leasing. I have delivered my share of 5-day notices and have tenants in your situation. First of all, who signed the lease? You? You and your spouse? The leases my owner uses requires a personal guarantee - so if you do not pay the rent you are at risk of loosing everything, including your house. Unless the antique dealers have a seperate lease agreements with the landlord, they are out too. As far as leaving your merchandise and fixtures, you need a lawyer. .
